48-CBSA-1.25X4.0X0.4 RF/IF and RFID

RF Shields are commonly used as a shielding barrier in numerous high-frequency applications. The type of shielded enclosure used is typically dependent on application parameters such as energy loss, power level, and operating frequency. One particular RF Shield that has recently been developed is referred to as the 48-CBSA-1.25X4.00X0.4.

This particular RF Shield is classified as a low-frequency RF Shield with a nominal frequency range of 1.25-4.0 GHz. The shielding effect of this shield is approximately 60-90 db, depending on the operating frequency. Additionally, the insertion loss of this shield is approximated to be in the range of 0.5-1.0 db depending on the application.

The application field for this particular low frequency RF Shield consists mostly of high power communications, such as radar systems, as well as industrial controls and security systems. Additionally, the 48-CBSA-1.25X4.00X0.4 RF Shield can be used to protect equipment from electromagnetic interference due to nearby sources, and it can also be used as a barrier to prevent the emission of RF energy from sensitive equipment.

The working principle behind the 48-CBSA-1.25X4.00X0.4 RF Shield is that it consists of three layers of conductive material that form a shield to block any type of incoming or outgoing RF energy. The outer layer consists of a conductive mesh that is coated with solder or copper. This layer acts as a barrier against the incoming signals or energy. The second inner layer consists of a conductive medium, such as copper or silver, and is responsible for dissipating and reflecting any RF energy that the mesh does not block.

The third and final layer of this RF Shield is an absorptive medium, typically made of carbon loaded rubber, foam, or cladding. This layer is responsible for absorbing any remaining energy that has been reflected or transmitted through the RF Shield. The combination of the mesh, conductive medium, and absorptive material is what creates the shield and offers protection from RF energy and signals.

The 48-CBSA-1.25X4.00X0.4 RF Shield is a great choice for many high-frequency applications, as it provides excellent shielding effectiveness and a very reliable shielding barrier. It is important to note, however, that this particular RF Shield is not suitable for applications that require very high-frequency signals or energy.
